You can create a scheduled task to change Storage DRS settings for a datastore cluster so that migrations for fully automated datastore clusters are more likely to occur during off-peak hours.

Before you begin

Enable Storage DRS.

About this task

You can create a scheduled task to change the automation level and aggressiveness level for a datastore cluster. For example, you might configure Storage DRS to run less aggressively during peak hours, when performance is a priority, to minimize the occurrence of storage migrations. During non-peak hours, Storage DRS can run in a more aggressive mode and be invoked more frequently.
